Pacific Northwest Laboratory is investigating the thermochemical conversion of high-moisture biomass feedstocks to high-Btu gas. Experimental results to date indicate that good yields of high quality gas (up to 52 vol % methane) can be produced. Carbon conversions after 15 min have exceeded 90 wt %, with methane yields in excess of 11.2 scf/lb (dry wt) of biomass. The reaction system utilizes low temperatures, high pressures, and a nickel/alkali carbonate catalyst mixture to effect the gasification of biomass slurries containing up to 95 wt % water. This paper discusses the role that alkali and nickel play in obtaining these results. The effect of their concentration on product yield and quality is discussed and explanations presented. In addition to gasification performance data for each of nine biomass feedstocks, elemental analyses, ash contents, and moisture contents of the raw feedstocks are presented. 10 refs., 4 figs., 5 tabs.
